We can export our current gear from the game to the website to get best in bags and optimized enchants and gems for that.
After you done that you can import the results back into the game to see what you need to change and which enchants to buy.
I think exporting the possible upgrades back for you and maybe your team back from the website into the game would be nice.
You could mark tradable drops , notify you should “roll on this item” , spend a seal on a certain boss and how much a certain item would increase dps healing and survivability for you and your mates.
Same true for the boe stuff on the AH.
